General Description
The PI325MC-A4 is a CIS module. It is a contact image sensor, using MOS image sensor
technology for high-speed performance and high sensitivity. The PI325MC-A4 is suitable
for scanning A4 size (216 mm) documents with 11.8 dots per millimeter resolution.
Applications includes fax machines, game systems, variety of mark readers, and other
automation equipment requiring document scanners.
Functional Description
The PI325MC-A4 imaging array consists of 27 sensors, PI3021 produced by Peripheral
Imaging Corp, that are cascaded to provide 2592 photo-detectors with their associated
multiplex switches, and a digital shift register that controls its sequential readout. Mounted
in the module is one-to-one graded indexed micro lens array that focuses the scanned
documents to image onto its sensing plane. The on-board amplifier processes the video
